. 'lhis'invention Vrelates to improvements in refrigerator car door operating mechanism. An object of the invention is to provide a vdoor yoperating devicenand fastener for a pair of pivoted refrigerator car doors, in which one ofthe doors isprovided with fas# tening means for securing it in closed position, and which door is provided with lever means swingablyinounted thereon nearrthe forward edge thereof, said lever means being .provided #with spaced v` engaging portions V adapted to eoact with the inner and outer Afacesof an. abutment member secured 'ad] acent the forward A'edge ofthe other door, whereby swinging movement of the lever means effects opening' and closing' movements of the doorupon -whichthe-abntment member is v`mounted.

- Other andfurtherjobjects of the invention l.Willinore clearly appear'froin the descrip tion and claims .hereinafter following.

In the drawings, Figure l isa vfragmentary kbrokei',1v.iewof, a refrigerator car, showing' the side doors in front'elevation, with the door fastening androperatingvmeans applied thereto; Figure 2 is a sectional View ofthe .invention on the line 2 2 of Figure l, showtion; And 'Figure 3 is' afraginentary sec? `tional View of the car loofrV sho-wing the lock# inn,` lever in side elevation. 'Referring' to the" drawings, and 6 'desigthe door @gouter edges andl door frame. A`As is V4custom- 5, which Visfthe first door closed, a Vwear plate 8 at its bottom .forward corner, saidV plategbeingiadapted 'to be engaged by the pivoted' latch 9 whenv the door is closed.` A The improveddoor operating mechanism j comprises an abutment rmember Argoperating lever Bgand'loclging Ameans C by .which the yoperating lever is lsecuijedin position.v

The abutment member A is in the `forinfof anv elongated inetallicplate, 'having av central web portion' 10, upon the 'longitudinal' 'edges of which are formed out-turned flanges 11 extending throughout the length of the abutment member, said abutment member at its rear end being,- provided with wings 12.

certain parts of the Vmechanism 'in elevan i lheabutment member is secured to the door ofthe door 6.a. suitable dis? plane of the faces off the doors when closed.

rThe outer fac'el of the curved portion lprevides *a* cam surface adapted for cooperation withthe lever means B, ashereinafterreferred tionll', and a channel on the outer face..

` to, the inner and outer faces of said projection `being"bounded adjacent their side edges'by the "flanges llwhich provide a pochetslike l recess on the inner face ofthe rcurved projec- TheV lever ineansB arefsecured to the door 5 horizontally in line with the abutment member Said lever means comprise a mounting bracket 17 substantially Lrectangular'in lfoi-in, each corner of the .brackethaving abfolt '18 exten'dinof therethrough byn'ieansl of which the bracket .is secured to the doorv 5. -rllie bracketl'l' provided witliupsstanding ears A 19419 adapted kforthe reception voffa pivot pin20, and between said ears, and extending somewhattoward the forward edgeofthe door 5, the bracket is cut out `as indicated at 2 1, for a purpose vwhich .willi-be hereinafter described, Mountedupon' the pivotpin20 are the lever means proper-,which include a liandlefportioii 22, and'apreversely 'entending off-v set acti'iating,I portion .23, The handle. portion. adj arent the pivot pin 20, is outwardlyciirved asindicated at 24, to providel what is ineifect an 'inner' canrijsurfaee 'adapted'- to"v (go-operate with the outer face i6'o'f the abutment inein-A f ber.V Forinedzintegrally with tlie;handle,'is

'the actuating' portion 23, said' portion being,` disposed on thesideof the pivot pin 2() opposite to the bearing portion 24 ofthe handle member and extending substantially parallel therewith, saidactuating portion" working' in the cutout part of thebracket 17 and: forming mi i with the bearing` portion 24 a recess 25 which is adapted tosnugly acrommodate lthe nose 26 ofthe abutment member A when the doors l' are in closed position. The handle portion 22` of the leve-r means -B is o f'such width that it `fits nicely between the flanges l10n the abut-l ment member whenthe doors are in closed Uhn lili

ositionA and the handle locked to the door 6 E the locking means C.` Y The lookin means Cinclude1 a mounting lug 2'? forme 5 abutment member, said ugbeing perforated for the reception of a pivot pin 28 upon which are mounted the forked ends of the lever 29, said lever being hung on the pivot pin so that it may depend across the outer end of the han- Y dle'22, and the lever 29 at the lower sideof the abutment member A is provided with an aperture 30 for the reception of a. keeperBl formed integrally with thelower wing 12 of vthe abutment Vmember, said keeper being adapted for the `reception of a locking element. A handle 32 is formed on the lever 29 whereby the same may be operated.

. l 1 operation, assuming the doors to be closed as illustrated in the drawings, in order to open the right-hand door, thelocking elemerit is detached from engagementwiththe keeper 31 so that the lever 29 may be lifted so .as to free the end of the handle 22. Outward swinging of the handleu22 effects outward i 25` swinging ofthe actuating portion 23 of the lever means which bears upon the curved surface 15of the vcurved projection 1.4, whereby f `the door 6 is forced outwardly7 a sufiicient dis- .V tance so that the' same may be thereafter swung to `fully opened position with little dif- Y ieulty',y The lefthand door may then be lopened byfreleasing the latch 9. In closing the door, the lefthand .door is irst slammed ,Shut and the latch turned to engaging position.v yThe righthanddoor is then swung in a closing direction, .and the nose ofthe abut` Ament member disposed between the actuating.

ever means B. The door ordinarily cannot be k.40 uconveniently fully closed because of the resistance-olfered'by the insulation between the the nose of the ahutmentmemberA, whereby continued movement of the handle 224 inwardf toward the car gradually forces the door to Y .L ully closed position, the handle 22 being then 5o- 4'secured by moving the lever 29 over the end of the same, and attachingthe locking'means.

lWhile I have herein shown' and described whatI now consider the preferred manner of vcarrying out my invention, the same .isinerely illustrative and Inconteinplate all changes and Y modifications that come within thevscope of` the claims appended hereto. `Ielaim: L v ,1. In a car door fastener, the combination u; with a pair of doors mounted .to swing about on theu per wing 12` of the- `p0rtion`23 and the curved portion 24 of the vertical axes and havingftlieirfree edgesy wadapted to abut in closed position; means for fastening one of said doors when the samev is in closed position;-v of l a f bracket mounted upon saiddooradjacenttheforward edges thereof, within the top and bottom edges thereof, .said lbracket being'pro` Vvided'with a pairy of vertically spaced upstanding ears'earrying a pivot pin; of an abutment member mounted adjacent the for-l -means thereon to pivotally support a locking lever atthe upper end, said widened portion at its lower end having an eyelet adapted` to engage an opening in said locking member; and a lever fitting within the channel' in said abutment member', the end ofsaid lever adjacent said locling member vbeing adapted to be'engaged by the' latter to lock 'the vsame in position, ytlieo'pposite end of said lever member being'pivotally mounted upon ther ivot pin on tie first mentioned'door, said ever being adaptedy to engage the outer sideof the nose of .said abutment member` and said c 'lever being provided with a reversely turned yav actuating portion adapted to engagethe in- Y ner Vside of the nose of said labutment member, whereby swinging movement of said lever `effects movement of said other door in openingfand closing directions.' Y .y

2. Ina car doorfastener, the ,combination with a -pairlof car doors mounted to swing about vertical axes Vand havingvtheir free edges adaptedfto abut in closed position;

of `anelongated lever having a body portionV and an integral reversely extending end portion Vspaced from lsaid Vbody por ioo tion, said lever member being" pivotally mounted adjacent` the forward edge of one" `door to 'swing about a vertical laxis locat-` ed between the Amainbody'l portion of the.V

leverand the reversely turnedportion; and

abutment means secured'rto the forwardedgeVv of theother door, said abutment means being provided with aprojection adapted to snugly lit between they reverselygturned lportion and body portion of said lever, vwhereby ,movement of said leverl eifects'movemcnt ofsaid doors in opening vand closing directions,j and maintains said ldoors in alignment when closed.
